The 1/2 inch BSP Plug provides a watertight seal for a 1/2 inch BSP fitting, measuring approximately 3.4 cm x 2.4 cm, and is used to test the water tightness of a given set of print settings by replacing a showerhead with the blanking plug and checking whether it can hold mains water pressure; the same print settings can then be used with some confidence for other watertight items. It is 3D printed using ABS plastic filament.

There is no sealing mechanism for the threads, so the connection will need PTFE tape, a liquid thread sealant (adhesive), or a rubber gasket; a rubber gasket already present in most shower heads can often be reused.

On some printers this part may not be watertight, so it is best to test before using it for anything critical. If it leaks through the threads, reduce the print scale slightly or use one of the sealing techniques described above. If the part is porous, try changing the print settings (higher hot end temperature, less fan, or more extrusion) or apply an acetone or lacquer treatment, ensuring any treatment is fully dry before retesting or use.

About the manuals

Field Ready develops manuals to support both the fabrication and safe use of its products. A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.
